I have a cousin that purposely goes to estate sales to buy what she calls "dead people's clothes" and that is all she wears. I know this is not quilt related but I just had to giggle a little at your posting.
I would love it if someone gave me a quilt with "antique" fabrics in it. I treasure the quilts that my mom and my grandma made and I inherited. Grandma's has silk flowers appliqued on it and the silk is shredding. I took it to an appraiser and asked what I could do about it and she said..."Honey, just enjoy it and know that your grandma loved you".
